CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No.15/462,716, filed Mar. 17, 2017, which claims the benefit of U.S.Provisional Patent Application No. 62/460,738, filed Feb. 17, 2017. Theentire contents of these applications are incorporated herein byreference.

FIELD OF THE INVENTION

This invention relates to the field of pest control and, moreparticularly, to a lighting device having an inner chamber for receivingpest control material and/or one or more sound emitters designed torepel pests.

BACKGROUND OF THE INVENTION

Various means exist for controlling pests, including insects androdents, in or around the home. For example, adhesive strips, sometimesreferred to as “glue traps” may be used to attract and eradicate pests.Pests may be attracted to a chemical attractant applied to a paper, andwhen a pest makes contact with the paper, an adhesive ensures that thepest remains stuck to the paper. Because pests cannot separatethemselves from the paper, they ultimately die of thirst, hunger, orage. Handling glue traps, however, may be difficult because the adhesiveis typically very strong and may inadvertently attach itself to theperson installing the glue trap. Also, the glue trap may need to beinstalled away from where persons are expected to walk so that it doesnot accidentally adhere to people or pets. However, placing the gluetrap in a remote location may reduce the likelihood that it will attractand trap pests.

Another means for addressing pests—typically insects—is by candles, suchas Citronella candles. The candles emit a scent that may repel insects.However, candles are a potential fire hazard and often produce unwantedsmoke and wax drippings.

Other existing devices for attracting and killing insects, sometimesreferred to as “bug zappers,” typically include a light sourcesurrounded by high-voltage, electrically charged metal elements. Manyflying insects, including mosquitos, are drawn to the light source, andare electrocuted when they make contact with the charged elements. Somebug zappers need to be placed on the floor or another flat surface andmay be accidentally contacted by persons or pets passing near the bugzapper. Certain bug zappers may be suspended from a post or a ceiling,but mounting the bug zappers can be difficult and/or time consuming, andmay still be accidentally contacted by persons passing near the bugzapper. Also, bug zappers typically need to be plugged into an electricsocket, further complicating installation.

Some existing lighting devices are capable of connecting to lightbulbsockets and emitting insect control material. For example, U.S. Pat. No.7,246,919, issued to Porchia et al., discloses a screw-in lightbulb witha dispenser that may be used to evaporate and emit fragrances and otheractive ingredients, including an insect control substance such as aninsecticide or insect attractant. However, the active ingredientdispenser is contained within the base and is not placed in proximity tothe light sources and/or used with an adhesive chemical to eradicateinsects. Also, the placement of insect control material near a ceilingor lamp light socket may not control pests that scurry along the floor,away from the insect control material.

There is therefore a need for improvements in pest control devices thatovercome some or all of the previously described drawbacks of prior pestcontrol options.

SUMMARY OF THE INVENTION

The present invention is directed to improved devices for pest control.

This invention describes a lighting device having a housing and an innermodule inserted within the housing of the device. The housing of thedevice has one or more light sources that may emit light in the visiblespectrum, infra-red spectrum, and/or the ultraviolet spectrum. Thespectrum of light may be chosen to attract or repel pests.

The inner module may be held within the housing by one or more magnets,screw threads that mate the inner module to the housing, and/or abayonet connection located at one end or both ends of the inner module.The inner module may include pest control material, such as a pestattractant, a pest repellant, and/or an adhesive. The inner module maybe removed from the housing and replaced with a new inner module. Theinner module may be replaced, for example, when the pest controlmaterial has evaporated or is no longer effective, or when a number ofpests have adhered to an adhesive within the inner module or applied toa surface of the inner module.

In an alternate embodiment, the invention describes a lighting devicehaving a housing and an inner chamber for receiving pest controlmaterial. The pest control material may include a pest attractant, apests repellant, and/or an adhesive. The pest control material may beremoved from the chamber and replaced with new pest control materialwhen, for example, the active ingredient of the pest control materialhas evaporated or is no longer effective, or when a number of pests haveadhered to an adhesive that is at least a part of the insect controlmaterial.

Numerous variations may be practiced in the preferred embodiment.

One or more light sources (40) may be capable ofemitting light in the ultraviolet or infrared spectrum. In addition orin the alternative, one or more light sources (40) may be capable ofemitting one or more colors in the visible light spectrum or a lightoutput at one or more light temperatures. For example, a light source(40) may emit yellow light. As a further example, the light temperaturemay be approximately 2700 K or 3500 K. The light emitted may attractpests, or may not attract pests. Each light source (40) may be connectedto and receive power from connector (22) and/or batteries in a batterycompartment within housing (12).

As depicted in FIG. 4, second end (30) may include a cover (32). Thecover may be translucent or transparent to allow light emitted from oneor more light sources (40) in the second end (30) to pass through cover(32). Cover (32) may be formed from colored translucent material, suchas plastic, that causes the emitted light to have a particular hue, suchas yellow. The type of light sources (40), the spectrum(s) of light,and/or the temperature(s) of light emitted from light sources (40) infirst end (20) may be the same type of light sources (40), spectrum(s)of light, and/or temperature(s) of light emitted from light sources (40)in second end (30). In the alternative, the type of light sources (40),the spectrum(s) of light, and/or the temperature(s) of light emittedfrom light sources (40) in first end (20) may be different than thelight sources (40), spectrum(s) of light, and/or temperature(s) of lightemitted from light sources (40) in second end (30). In addition, eachlight source (40) within each end (20, 30) may be different and/or mayemit different spectrum(s) of light, and/or temperature(s) of light thanthe other light sources (40) in that end (20, 30).

As shown in FIGS. 2 and 4, second end (30) may have an aperture (36)leading to the open, center region of housing (12), between first end(20) and second end (30). To the extent that second end (30) includes acover (32), cover (32) may have an aperture (33) of the same shape andsize as aperture (36). Aperture (33) may align with aperture (36) whencover (32) is applied to second end (30).

First end (20) may further include one or more magnets (24). As shown inFIG. 3, the one or more magnets may be preferably aligned with thecenter axis of first end (20). Also, as shown in FIG. 3, the one or moremagnets may be located within a recess at the bottom surface of firstend (20). In the alternative, first end (20) may have a flat bottomsurface and one or more magnets (24) attached to the bottom surface.

As shown in FIGS. 10, 12A, and 12B, second end (30) may include bayonetconnection receptor slots (240). In addition or in the alternative,bayonet connection receptor slots may be included in first end (20).

Proximal end (62,262) may have a magnet (64, 264) at or near the surface. Magnet (64,264) may be magnetically attracted to magnet (24) in first end (20) ofhousing (12). Proximal end (62, 262) of inner module (60, 260) may beinserted through aperture (36) in second end (30).

As shown in FIG. 6, inner module (60, 260) may be fully inserted intohousing (12) so that, for example, the distal end (66, 266) of innermodule (60, 260) is situated within aperture (36) of second end (30). Inthe alternative, a portion of inner module (60, 260) may remain outsidehousing (12) when inner module (60, 260) is fully inserted, or distalend (66, 266) of inner module (60, 260) may be located some distanceinto housing (12) when inner module (60, 260) is fully inserted intohousing (12). Inner module (60) is shown in FIG. 1 as partly insertedinto housing (12). The arrows in FIG. 1 indicate the direction in whichinner module (60, 260) may be inserted into housing (12).

Preferably, inner module (60, 260) may be inserted into housing (12) tothe point where magnet (24) of first end (20) and magnet (64, 264) ofinner module (60, 260) are in sufficiently close proximity to each otherto create an attraction between magnet (24) and magnet (64, 264) strongenough to prevent inner module (60, 260) from falling out of housing(12) when first end (20) of housing (12) is oriented directly abovesecond end (30) of housing (12), or when proximal end (62, 262) of innermodule (60, 260) is oriented directly above distal end (66, 266) ofinner module (60, 260).

In the alternative, magnet (24) of first end (20) of housing (12), ormagnet (64, 264) at proximal end (62, 262) of inner module (60, 260) maybe replaced by a metal attracted to a magnet (ferromagnetic).Preferably, the strength of the magnet and the size of the ferromagneticmaterial would be sufficient to prevent inner module (60, 260) fromfalling when housing (12) and/or inner module (60, 260) are oriented asdescribed in the preceding paragraph.

In addition to magnet (24) and/or magnet (64, 264), or in thealternative, inner module (60, 260) may have one or more bayonetconnection pins (270) at proximal end (62, 262) and/or at distal end(66, 266) that are capable of mating with bayonet connection receptorslots (240) in the first end (20) and/or the second end (30).

In the alternative, proximal end (62, 262) and/or distal end (66, 266)of inner module (60, 260) may include screw threads (not shown) that arecapable of mating with screw threads at first end (20) of housing (12)and/or within aperture (36), respectively. Inner module (60, 260) maythen be secured in housing (12) by engaging the screw threads of innermodule (60, 260) with the screw threads at first end (20) of housing(12) and/or within aperture (36).

The distal end (66, 266) of inner module (60, 260) may have a handle(68, 268), a hole (70) (see FIG. 6), a notch, or other means forgripping distal end (66, 266) to facilitate removal of inner module (60,260) from housing (12). In addition or in the alternative, at distal end(66) may include one or more magnets magnetically attracted to magnet(24), to allow inner module (60) to be magnetically held within housing(12) as described above regardless of whether the proximal end (62) orthe distal end (66) are inserted first into housing (12).

As shown in FIG. 7, inner module (60) may comprise a sheet of flexiblematerial (70) wound around at least a center post (76). The sheet ofmaterial (70) may be longer than the circumference of center post (76),and may be unrolled to expose more of sheet (70). One or more of thepillars (50) or (52) may include ridges or edges that may be used tofacilitate tearing sheet (70).

Sheet (70) may be coated with pest control material. The pest controlmaterial may be an insect attractant or an insect repellant. The pestcontrol material may include, instead or in addition, an adhesivematerial capable of binding to the sheet insects that land on the sheet.The pest control material may comprise a mix of ammonia, L-lactic acid,tetradecanoic acid, 3-methyl-1-butanol and 1-butylamine. The pestcontrol material may further include octanol.

In an alternative embodiment, pest control material may be applieddirectly to the surface of the inner module (60). In that embodiment,inner module (60) would preferably have an absorbent surface to retainthe pest control material.

As shown in FIGS. 8A-8B, the center portion of inner module (60) mayconsist of one or more interlocking cards (78). Preferably, inner module(60) would include two to four cards (78). Three cards (78) are shown inFIGS. 8A-8B. FIG. 8B shows the three cards (78) from FIG. 8A assembledas the center portion of inner module (60). The cards (78) may be coatedwith pest control material. The cards (78) may be connected to proximalend (62) and distal end (66) of inner module (60) by an adhesive, or byinserting the ends of cards (78) into corresponding recesses in theinner facing surfaces of proximal end (62) and distal end (66). As shownin FIGS. 9A-9C, inner module (60) may include pillars (82) from proximalend (62) to distal end (66) that, for example, provide rigidity to innermodule (60), help facilitate insertion of inner module (60) into housing(12), and help prevent inadvertent contact with cards (78).

As shown in FIGS. 10, 11, 13A and 13B, inner module (260) may comprise achamber capable of receiving pest control material. The chamber may havea cylindrical shape, a rectangular shape or any other shape. Preferably,the chamber is the same shape as aperture (36). The walls of the chambermay be perforated with one or more holes (267) that may allow air topass through them. The circulation of air through holes (267) mayfacilitate dispersing the pest control material inserted within thechamber. As discussed above, inner module (260) extends from proximalend (262) to distal end (266). A magnet (264) may be located at proximalend (262). In addition, or in the alternative, inner module (260) mayhave one or more bayonet connection pins (270) at proximal end (262) orat distal end (266) that are capable of mating with bayonet connectionreceptor slots (240) in the first end (20) and/or the second end (30) ofhousing (12). In the alternative, proximal end (262) and/or distal end(266) of inner module (260) may include screw threads (not shown) thatare capable of mating with screw threads at first end (20) of housing(12) and/or within aperture (36), respectively.

In an alternate embodiment of the invention, instead of inserting aninner module into the lighting device, a chamber capable of receivingpest control material may be situated within the central region ofhousing (12). The chamber may extend from first end (20) to second end(30) of housing (12). The chamber may have a cylindrical shape, arectangular shape or any other shape. The chamber may be perforated withone or more holes that may allow air to pass through them. Thecirculation of air through the holes may facilitate dispersing the pestcontrol material inserted within the chamber. Pest control material maybe inserted into the chamber through aperture (36) of second end (30),and may be contained within the chamber by a door or cap sealingaperture (36).

The pest control material may be an insect attractant, an insectrepellant, and/or an adhesive. The pest control material may be removedfrom the chamber and replaced with new pest control material when, forexample, the active ingredient of the pest control material hasevaporated or is no longer effective, or when a number of insects haveadhered to an adhesive that is at least a part of the pest controlmaterial.

The lighting device may further have one or more sound emittingcomponents. An example of a commercially available sound emittingcomponent can be found in the Aspectek Home Sentinel 5-in-1 IndoorUltrasonic and Electromagnetic Pest Repellent. The sound emittingcomponent(s) may be located within first end (20) and/or second end (30)of the housing (12). Each sound emitting component may comprise a soundgenerator and a speaker. Housing (12) may have one or more apertures orvents to facilitate emission of sound from the sound emittingcomponents. The apertures or vents may also facilitate air circulationaround the sound emitting components to enhance convection of heat awayfrom the sound emitting components. For example, sound emittingcomponents may be located within second end (30) and apertures or ventsmay be located on the surface of the second end (30) facing the firstend (20).

Each sound emitting component may be capable of generating an ultrasonicsound. The ultrasonic sound may be in the form of short wavelength, highfrequency sound waves that are too high in pitch to be heard by thehuman ear. For example, the sound emitted may have a frequency greaterthan 20,000 Hz. Because some animals, such as bats, dogs, rodents, andsome insects, such as grasshoppers and locusts, can hear well into theultrasonic range, the sound may repel insects and pests, while remaininginaudible to humans.

Lighting device (10) may further include one or more circuit boardselectrically connected to the light sources (40) and/or sound emittingcomponents, and electrically connected to connector (22) and/orbatteries. The circuit board may be used to control the illumination oflight sources (40) and/or the sound emitted from the sound emittingcomponents. The circuit boards may control, for example, the brightnessof one or more light sources (40) and/or the spectrum or temperature oflight emitted by one or more light sources (40). The circuit boards mayalso control, for example, the frequency of sound emitted from the soundemitting components. Each circuit board may be contained within firstend (20) or second end (30) of lighting device (10).
